Zero murrs softly once feeling his sister's delicate paws on his rump again before he smirks darkly. "Ooh? Is that a challenge dear sister?" He softly said before swiftly rolling down with her, having her under him once again. Zero looked into Nina's eyes, while resting his paws on the bed for some support. "You truly want to check out if my workouts paid off?" And before waiting for Nina to reply, Zero starts moving his hips, thrusting gently at first, moaning softly, his member throbbing inside her.
